UART overview

Flexible single and multi-channel devices make it easier to add UART to your design

Flexible solutions

Discrete UART solutions provide flexible baud rates, lower current consumption and programmable features

Deeper FIFO memory

First-in, first-out memory up to 64 bytes lets you offload data from an MCU, freeing up valuable processing bandwidth

Multiple channel-count options

Single, dual- and quad-channel offerings to meet varying needs of multiple applications

Featured UART devices


Dual-channel UART with 64-byte FIFOs, automatic hardware and software flow control, and data rates up to 3 Mbps


Four-channel UART with 16-byte FIFOs, enhanced features, and data rates up to 1 Mbps


Serial infrared (SIR) encoder and decoder that encodes and decodes serial data in conformance with the IrDA specification
